Bureau Veritas classe six Suezmax gas-prepared

Marine Marchande

 Leading international classification society Bureau Veritas is to grant GAS-PREPARED notation to six Suezmax tankers under construction for Dynacom Tankers Management. The oil tanker specialist is the first shipowner to future-proof its vessels by applying for the notation. 

The 157,000 dwt tankers will measure 274.3 meters in length, with a beam of 48 meters and depth of 23.2 meters. They are being built at New Times Shipbuilding in China, with  delivery expected in 2017 and 2018. 

The GAS-PREPARED notation sets out requirements for ships which are designed and fitted out for dual-fuel or LNG fuel propulsion, but which are not initially intended to use gas as a fuel. It provides owners with the flexibility to convert easily to dual fuel or LNG fuel propulsion in the future. 

Jean-François Segretain, Marine & Offshore Technical Director, Bureau Veritas said: 

“Using natural gas as fuel enables owners to comply with the requirements of Emission Control Areas in North America and Europe, and can be cost-effective in the long term. In publishing the GAS-PREPARED notation, Bureau Veritas sought to provide owners with the ability to switch to LNG in the future when market conditions are right. 

Applying for GAS-PREPARED is an important step in future-proofing a new vessel and we look forward to working with Dynacom, the first owner in the market to choose this solution.” 

Bureau Veritas’ Rule Note NR 627 Gas-Prepared Ships, published in late 2015, sets out how the initial design of the ship is to take into account the necessary spaces or zones to accommodate the following installations: 
• LNG bunkering station 
• LNG storage tanks 
• Fuel gas handling system 
• Ventilation systems 
• GVU 
• GCU, where required by NR529 
• Vent mast. 

Vessels meeting the standards are awarded the notation Gas-Prepared. 
The notation may be modified with the addition of: 
• S when specific arrangements are implemented for the ship structure 
• P when specific arrangements are implemented for piping 
• ME-DF when the main engine(s) is (are) of the dual-fuel type 
• AEB when the auxiliary engines and oil-fired boilers are either of the dual fuel type, or designed for future conversion to dual fuel operation.
